Iguazu Falls flow 3,613 m³/s: what to expect this week
Guia 3 newsroom · edited by Annie GrellmannPortuguêsEspañol
The flow of the Iguaçu River at the Falls is 3,613 m³/s, almost 2.4 times the historic average of 1,500 m³/s.
The measurement of 3,613 m³/s equals 2.4 times the historic average of the river (1,500 m³/s, or 1.5 million liters per second). Visually, this corresponds to about 1.4 Olympic-size swimming pools dropping every second or 361 water-tanker trucks per second. The water level is well above normal, ranking among the top 5% of values ever recorded in the Guia 3 series since June 2026.
With such a strong current, the waterfall creates a lot of mist on the walkways and an even more intense spectacle at the falls. The viewpoints remain open, but the final section of the Devil’s Throat walkway may be temporarily closed for safety – the decision is made by the park on the day of the visit. Therefore, before you go, check the real-time status at /cataratas-hoje.
The water appears brown due to sediment brought by rain in the river basin, not because of dirt. This flood is unrelated to the Itaipu dam, which is on the Paraná River and does not control the flow of the Falls.
What this means for you:
- Wear clothing and shoes that can handle extra moisture and splashes;
- Bring a raincoat or poncho, as the mist can get you wet quickly;
- If you want to arrive early, go in the early morning hours to avoid lines and enjoy clearer light;
- Check the final walkway closure on the official website before leaving home.
